United Air, FedEx offer overnight baggage shipping

United Airlines is teaming with FedEx Corp. to ship a passenger’s bag overnight for as much as $358 roundtrip, betting that some customers will pay the higher cost to avoid taking luggage to the airport.

Travelers would get door-to-door baggage handling and avoid the wait at airport luggage carousels, as well as the airline’s fee of $30 to check one bag roundtrip. The new option’s cost exceeds the $130 roundtrip fee to check two bags with United, a unit of Chicago-based UAL Corp.
